Methob  of ornamentinq walls or ceflings



sunken ligure with raised edges or lips, the pebbles remaining grouped or scattered in and around the concave.l as required. This grouping is varied with fine `effect when coarse gravel is used by throwing in a ii ner grade of gravei in and about the same. After the large gravel is placed, unique effects are` background for any desired surface herein.

' described.

When geometrical or conventional sunkfignre work is required for artistic effects,

well-oiled wooden stencils, patterns, or mod-` els of the desired thickness and hind are sunk into the plastic surface of the second or cement hair coat. Such surface is then roughened or manipulated with a sponge, and when required the surface is treated in gravel, as above described. The stencils or models are removed when the work is suiiicently h'arden'ed or set.

' \Vhen geometrical or conventional erna mentation of a raised character is required, then paper or other pliable stencils are' laid on the plastic surface of Ithe coment hair mor-y tar, andthe cement and gravel, when mixed tothe desired consistency, are throwninto the nterstices ofthe stencil until the required raised figure is obtained.

Irregular and interlacing gravel effects are 4'produced by mixing suicient cement and 'gravel with water to the right consistency and by 'building or throwing the preparation from the point of the trowel upon the plastic surface until the'required outline and inter lacing effect is produced.

When the abovedescribed surfaces are to be more uniformly pebble-graded .or roughened, then dry gravel is mixed with dry cement, which, when hurled or thrown into or between the intcrstices of the coarser grav- ,-eled surfaces, seatters'more uniformly and gives to the general surface and grouping a naturally roughened edect, which permits better artistic treatment in the .coloring and f br'onzingI of the, said surface. e

When a panel or other'sunken orjnserted figure is to be formed, I employ xod` and movable grounds'. The xed grounds are employed to plaster to in the usual way; but

the movablegrounds a e employed not only to yplaster to as a boun ary-line, but to preserve the bed, yeline, and surfaceA for the casings, styles, and moldings, and to preserve `the places'for any desired gure, as, i1lustrated by the block shown in Fig. 3 and the groove and exposed latli shoivn in Fig. 4. In such case the ground or pattern is attached to the lath and the plastering donc all around l it, and it is then removed and the required `tinish put into the space so lefti W hen a raisedfigure of largeproportion is to be constructed, then a wire-ganze or other suitable frame-work is employed as a foundation for the plastic work.

When concreted pebble surfaces require*r some sp'eeial or a heavier grade in surface treatment, the first coat or scratch-coat is allowed to suiciently dry to cause more-ab-l sorption, when the second cement hair-mortar coat is'applied.

In all cases in the foregoing specification where cement is mentioned, plaster-of-paris or otherlike materialmay be used. I therefore do not confine myself to the use of` cement Having thus described my invention, what I claim, and desire ton secure by Letters Patent., is

The herein-described method of ornamenting walls and ceilings, which consists' ,in applying; a plastic coat thereto, and while said coat is wet dashing; or hurlingforcibly into it gravel, cement, plasterofparis, or the like,
